DEFINITION

Classification: 427/475

Solid particles or atomized liquid applied:

(under subclass 458) Processes wherein solid particles are sprayed or liquid particles are atomized and sprayed into the vicinity of the substrate and are electrostatically attracted thereto.

(1) Note. The particles may form the coating, or become part of a coating as when applied over a layer of adhesive.
